EEG Labs

EEG Labs - What happens in the brain?

The EEG Labs provide insights into what happens in a person's brain in certain situations. EEG stands for Electroencephalography (EEG), which accurately records brain activity in real time. In the EBL, brain activity can be measured at high spatial resolution and high frequency using active electrodes.

A special cap is placed on the head with several (32 or 64) electrode holders. These holders are filled with gel, after which active electrodes are placed in them. This allows someone's brain activity to be accurately measured in real time during a test. After analysing the raw data, researchers obtain insight into the effects of attention, how memory works, the influence of language and emotions, as well as how addiction works, for example.

The four EEG Labs in the Erasmus Behavioural Lab are multifunctional research areas with nearly unlimited possibilities to study human cognition. The data picked up by the electrodes can be analysed and if desired, translated into digital images of the brain activity using special software. In this way, a kind of ultrasound of the brain is produced during the test. The EEG Lab makes it possible to obtain insight into our brain's activity.

EEG Lab specs:
